But he pays a lot of attention while driving on the old track, the process of "prince" of colonization. No one doubts that the princes took care of the military security of the edge and they had to strengthen the settlements, to build a "city." But the role of the southern Russian princes as "colonizers" in the overall settlement of the Slavs edge was very limited. It is very likely that they took steps that helped move Vladimira- Zaleski and Bogolyubov. But we suppose that the princes successfully fought with the opposition circles of the local feudal lords, not because they are the princes were "colonizers", but because they are in the Northeast have found the social environment (city dwellers and landowners), which could rely on. We had to point out at the same time a certain catalytic role of the southern Russian princes in the development of feudal tenure in the Northeast in the spread of the boyars, the princes, the church and the monastery, "sat down" (see.
